Hi Guys
I am a newby here so excuse me if I say anything dumb

I am looking for advice on the suitability of using a Umimog in Papua New Guinea and if so how I would go about getting one that suits at a reasonable price
I am involved with a few of the locals in PNG that are using a few old Troopys to ferry people between 2 remote villages. The Troopys are old but there is really nothing you cant fix on them, which is advantage.
The prob is that they are really costing them a fortune to maintain and I think the that even though the troopys are good they are still being asked more of then they are capable to do on a regular basis.
There are several creek crossings that have to be negotiated and of which the worst is about a1-1.2 m deep, it does get deeper than that but they don't bother trying in those conditions.
I'll leave the explanation there as I think all will have the gist,
One last thing I would like to point out is that we are not really concerned about how the unit works as we are not enthusiast as such, wnd willing to trade looks for price, priority is that it does the job and will continue to do it if it is regularly serviced and mechanically maintained
Appreciate any advice and anything else I should know
Have a few questions as follows
Would a Unimog be a good choice to do this job?
Would Frontline Auctions be a good place to source one, if not where?
Are the Unimogs easy and affordable to service?
Where would be the best place to buy regular service item ie filters etc and what would I expect to pay
Considering the work it is doing, how often would it need to be serviced are there any guidelines available I should follow
How much can I expect to pay for one at auction that could do the job
Is there any one or company that I can call on to give me an opinion on vehicles to be auctioned ( all care but no responsibility of coarse)
Anyway there is a good start, like I said appreciate any pointers I am given
All the best
